I seriously advise against anyone bleaching their own hair, especially with professional strength products like the ones at Sally's, unless you are experienced with it. If you don't leave it on long enough, you will end up with clown hair. Leave it on too long and your hair will be totally fried. Sometimes you'll get fried clown hair, depending on how healthy your hair was prior to bleaching. It's so hard to fix that mistake too. You can try to dye over it, making it a darker color, but the dye could take unevenly or turn out differently than it was supposed to. I walked around with moss greenish brown and grayish hair for 3 days after I tried to dye my bleached-out mess dark blonde. Another time, I didn't get the bleach on evenly and ended up with hair that was the same color and pattern of an orange and brown calico cat.
Just my input tho. I've messed my own hair up more times than I care to count. And color correction at a salon will run you around $200+. And once you screw up, you more than likely WILL end up there. I say save yourself at least $150 and get your hair dyed at a salon.
